| contents | How do nickel, cadmium, and lead nanoclusters interact with boron-nitride and Mobius-type boron-nitride nanobelts? To answer this question, we used the semiempirical tight binding framework, as implemented in the xTB software, to determine the lowest energy geometries, binding energy, complexes stability, and electronic properties. Our calculations show that heavy metal nanoclusters favorably bind to both boron-nitride nanobelts, although the interaction is stronger with the Mobius-type nanobelt. The calculations show that the nickel nanocluster has the lowest binding energy and the greatest charge transfer with the nanobelts, followed by the cadmium and lead nanoclusters. During the simulation time, the molecular dynamic simulation showed that all complexes were stable at 298 K. Following the nanobelt's symmetry, the frontier orbitals are distributed homogeneously throughout the structure. This distribution changed when the nanobelt was twisted to create the Mobius-type nanobelt. The topological study indicated that the number of bonds between the metal nanoclusters and the Mobius-type nanobelt doubled and that the bonds formed with the nickel nanocluster were stronger than those formed with the cadmium and lead metals. Combining all the results, we conclude that the nickel nanoclusters are chemisorbed, whereas the cadmium and lead nanoclusters are physisorbed in both nanobelts. |
